Description
技术领域
本发明涉及材料领域,具体涉及一种耐高温腐蚀匣钵及其制备方法。
背景技术
碳化硅由于化学性能稳定、导热系数高、热膨胀系数小、耐磨性能好,例如:以特殊工艺把碳化硅粉末涂布于水轮机叶轮或汽缸体的内壁,可提高其耐磨性而延长使用寿命1~2倍;用以制成的高级耐火材料,耐热震、体积小、重量轻而强度高,节能效果好。低品级碳化硅(含SiC约85%)是极好的脱氧剂,用它可加快炼钢速度,并便于控制化学成分,提高钢的质量。此外,碳化硅还大量用于制作电热元件硅碳棒。因此为了提高耐高温性能,碳化硅常被使用于制备锂电池正极材料匣钵,从而增加了匣钵的耐高温性能。但是锂电池正极材料匣钵仍存在着抗侵蚀性差的问题,用于焙烧的锂电池正极材料多为粉末状,渗透能力强,材料中的锂离子属于强碱性物质,强碱物质对匣钵材料具有很强的侵蚀性,锂电池正极材料焙烧过程中,由于锂离子与匣钵的接触过程中,锂离子能够将匣钵中的Si、Al、Mg等离子析出,从而破坏匣钵的微观结构,匣钵遭受到侵蚀,导致匣钵的使用寿命明显缩短。同时匣钵经过2000-2500℃的高温冷热重复使用,一般使用20-30次就会报废。同时由于匣钵内的氧化物氧化性能高,且还具有强酸强碱的特性,很容易被腐蚀。高温强腐蚀的大大降低了匣钵的使用寿命。
目前为了改善匣钵的抗腐蚀性能,一般常用的方式是在匣钵的表面涂抹一层防腐材料;如公开号CN110452605A公开的一种碳化硅涂料及其制造方法,包括碳化硅粉末30~40%、水性聚氨酯20~30%、聚丙烯酸酯10~20%、有机金属盐5~15%、凹凸棒土1~10%、纤维素衍生物1~5%、水性润湿剂1~5%、甲醇1~5%。在匣钵高温的反如下,有机物中的结晶水容易蒸发,且有机物呈现熔融状态;使涂层容易脱落,影响防腐效果;同时脱落的涂层影响电极的导电性能。公开号CN110451939A公开的一种匣钵及其制造方法,其匣钵材料主要包括高岭土8-10份,滑石7-9份,氧化铝4-6份,粒径10μm-40μm的刚玉22-28份,粒径0.1-0.8mm的刚玉45-58份,粒径300-500目碳化硅18-30份,莫来石8-15份以及粒径为0.1-1mm的堇青石8-16份,其中高岭土中二氧化硅的质量百分比为50%,三氧化二铝的质量百分比为38%;滑石中二氧化硅的质量百分比为55%,氧化镁的质量百分比为35%。其制备方法通过水的混合,同时加入了结合剂,结合剂为纸浆废液或聚乙烯醇或糊精。本发明中的结合剂虽然在常温下具有站街作用,但是在高温下容易糊化,很难将无机物粘接在一起,降低了匣钵的质量。
综上所述,现有技术中虽然有利用碳化硅对匣钵防腐和耐高温,但作为涂料方式的碳化硅防腐材料容易脱落,影响防腐效果;而添加性的匣钵中其中的粘接剂效果不好,容易产生空隙和气泡,影响了匣钵的品质。
